Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional assembling process is used for lens barrels, then assembly is simple and fast, but alignment precision between lenses and light sensor chip deteriorates due to uncorrectable tolerances
Solution Approach 1:
The patent applies preliminary action by pre-assembling the lens module with adjustable mechanisms before final assembly. The lens barrel is equipped with adjustment mechanisms that allow alignment correction to be performed in advance, ensuring precise positioning of lenses relative to the light sensor chip before the module is integrated into the camera device.
Solution Approach 2:
The patent implements dynamics by introducing adjustable and movable components into the lens barrel assembly. The lens barrel includes adjustment mechanisms that enable dynamic positioning of lenses along multiple axes, allowing alignment precision to be optimized during the assembly process rather than being fixed by conventional rigid assembly tolerances.
2Reliability
If conventional assembling process is used, then production speed is maintained, but image quality deteriorates due to assembly errors causing lens eccentricity and tilt
Solution Approach 1:
The patent applies preliminary action by performing alignment adjustment in the lens module assembly stage before final integration. This preliminary positioning ensures that lenses are correctly aligned with the light sensor chip, preventing image quality deterioration from eccentricity and tilt while maintaining production efficiency through streamlined assembly.
Solution Approach 2:
The patent replaces conventional mechanical assembly with precision-adjustment mechanisms. Instead of relying solely on mechanical tolerance stacking, the invention uses adjustable positioning systems with multiple degrees of freedom to achieve precise alignment, thereby improving image quality without significantly impacting production efficiency.
3Manufacturing precision
If lens positions are fixed during assembly, then assembly is straightforward, but optical quality deteriorates due to inability to correct alignment errors
Solution Approach 1:
The patent implements dynamics by providing adjustable lens positions within the lens barrel. The adjustment mechanisms allow lenses to be positioned dynamically along multiple axes during assembly and calibration, enabling precise optical alignment while maintaining ease of manufacture through standardized adjustment procedures.
Solution Approach 2:
The patent applies parameter changes by enabling adjustment of lens position parameters (coordinates along X, Y, Z axes and angular orientations) during assembly. This allows optimization of optical alignment parameters without complicating the manufacturing process, as the adjustment mechanisms are integrated into the lens barrel design.
4Manufacturing precision
If multiple separate calibration steps are performed after assembly, then alignment precision can be improved, but production time and cost increase
Solution Approach 1:
The patent merges the calibration function into the lens module assembly itself. The adjustment mechanisms are integrated into the lens barrel structure, allowing alignment calibration to be performed during the assembly process rather than requiring separate post-assembly calibration steps, thereby reducing production time while maintaining high alignment precision.
Solution Approach 2:
The patent applies preliminary action by performing alignment calibration during the lens module assembly stage before final integration into the camera device. This preliminary calibration ensures optimal optical alignment is achieved early in the manufacturing process, eliminating the need for time-consuming separate calibration steps later.
